Primes¶
- Diagnostically Inert Signal
- Clinical alarms: code-blue announcements that broadcast a location without specifying patient state; the alarm-fatigue literature is a direct response to channel-content inertness.
This sourceReviews clinical alarm fatigue — high-rate alarms that announce a state without actionable content, inducing rational learned ignoring (the recipient pathology of channel-content inertness).
Supported in partVerified against the work's full text
Cvach documents ICU monitor alarm fatigue (up to 700 alarms per patient per day, desensitization), but not the target/cause/action/escalation payload model or 'rational' ignoring.
“Alarm fatigue, the lack of response due to excessive numbers of alarms resulting in sensory overload and desensitization, is a national problem.”

- Monitoring
- This requires iterative calibration based on incident history and false-alarm rates, and often involves machine learning to identify which alerts correlate with actual patient deterioration.
This sourceIntegrative review of 72 studies on hospital monitor alarms; documents that approximately 70% of nurses report alarm desensitization and synthesizes evidence on threshold tuning and alarm-management strategies to prevent fatigue.

Cvach supports data-informed tuning of alarm limits and algorithmic false-alarm reduction, but not iterative calibration from incident history or ML tied to deterioration.
“Alarm data informs proper settings for unit default parameter limits, assists in determining alarm prioritization, and reduces alarm fatigue.”
- This requires iterative calibration based on incident history and false-alarm rates, and often involves machine learning to identify which alerts correlate with actual patient deterioration.
- Signal Inflation
- In critical-care medicine it is alarm fatigue: cardiac monitors fire so many false positives that clinicians silence or ignore them and genuine arrests are missed.
This sourceReviews cardiac-monitor alarm fatigue: high false-alarm rates train clinicians to silence or ignore alarms, so true events are missed.
SupportedVerified against the work's full text
Cvach's review links excessive false monitor alarms to staff silencing or ignoring them, so real events go unanswered, citing FDA reports of alarm-related deaths.
“Excessive false positive alarms result in caregiver apathy and desensitization such that real events are less likely to be acted upon.”

- Alert Suppression and Rotation Workflow

- Alert Threshold
- Its signature failure is alert fatigue: tune the level too sensitively or skip the persistence window, and it pages so often — mostly on noise — that recipients start ignoring it, at which point the one page that mattered is lost in the pile.
This sourceLinks tight thresholds and absent delays to excessive low-value alarms, desensitization, and reduced response.

This sourceShows how excessive nuisance alarms desensitize caregivers, encourage ignored warnings, and contribute to missed consequential alarms.

- Push the alert-salience floor too low and you manufacture the opposite problem — alarm fatigue, where so much is styled as urgent that operators learn to ignore all of it, and a real breach is tuned out like the rest.

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Read against the text for 4 of 23 citations: 1 supported, 3 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
